vc4: Move simulator memory management to a u_mm.h heap.
Now we aren't limited to 256MB total allocated across a driver instance,
just 256MB at one time. We're still copying in and out, which should get
fixed.

vc4: Add a bitmap of branch targets in kernel validation.
This isn't used yet, it's just a first step toward loop validation.
During the main parsing of instructions, we need to know when we hit a new
basic block so that we can reset validated state.

vc4: Move tile state/alloc allocation into the kernel.
This avoids a security issue where userspace could have written the tile
state/tile alloc behind the GPU's back, and will apparently be necessary
for fixing stability bugs (tile state buffers are missing some top bits
for the tile alloc's address).

vc4: Handle refcounting the exec BO like we do in the kernel.
This reduces the diff to the kernel, and will be useful when I make the
kernel allocate more BOs as part of validation.

vc4: Update to current kernel sources.
New BO create and mmap ioctls are added. The submit ABI gains a flags
argument, and the pointers are fixed at 64-bit. Shaders are now fixed at
the start of their BOs.

We don't care if things like vertex data get smashed by render target
data, but we do need to make sure that shader code doesn't get rendered
to.

VBOs as shader code.

vc4: Rewrite the kernel ABI to support texture uniform relocation.
This required building a shader parser that would walk the program to find
where the texturing-related uniforms are in the uniforms stream.
Note that as of this commit, a new kernel is required for rendering on
actual VC4 hardware (currently that commit is named "drm/vc4: Introduce
shader validation and better command stream validation.", but is likely to
be squashed as part of an eventual merge of the kernel driver).

vc4: Switch simulator to using kernel validator
This ensures that when I'm using the simulator, I get a closer match to
what behavior on real hardware will be. It lets me rapidly iterate on the
kernel validation code (which otherwise has a several-minute turnaround
time), and helps catch buffer overflow bugs in the userspace driver
faster.
